Key Applications Flow Cytometry
Frozen Sections
Gel Shift
Immunoblotting (Western Blotting)
Immunofluorescence
Immunoprecipitation
Application NotesFrozen Sections (10 µg/ml, see application references)
Gel Shift (see comments)
Immunoblotting (10 µg/ml, see application references)
Immunofluorescence (1-20 µg/ml, see application references)
Flow Cytometry (1-20 µg/ml)
Immunoprecipitation (1 µg per sample, see application references)
Application CommentsOriginally called clone L21. Does not recognize phosphorylated or acetylated p53. For a gel shift assay, resuspend in 100 µl buffer. Wild-type p53 has a short half-life and is present in low amounts in cells. For immunoprecipitation, increasing the amount of sample to be immunoprecipitated and applied to the gel may help visualize wild-type p53, and short incubation times with 35S-Met (≤1 h) will help reduce background. For immunoblotting wild-type p53, maximize sensitivity by concentrating samples by immunoprecipitation with Cat. No. OP03, then perform immunoblotting using Cat. No. PC35 and chemiluminescent detection. Antibody should be titrated for optimal results in individual systems.

Special InstructionsReconstitute the lyophilized antibody with sterile PBS, pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 100 µg/ml. Lyophilized antibody should be resuspended at 4°C with occasional gentle mixing for at least 2 h. Store at 4°C until reconstituted, then store in aliquots at -20°C or at 4°C with 0.1% azide; freezing of aliquots is best for long-term storage of reconstituted product, but repetitive freezing and thawing should be avoided.

DescriptionPurified mouse monoclonal antibody, originally called clone L21, generated by immunizing mice with the specified immunogen and fusing splenocytes with NS1 mouse myeloma cells (see application references). Recognizes the ~53 kDa wild-type and mutant forms of p53.
BackgroundThe human p53 tumor suppressor gene encodes a 393 amino acid phosphoprotein that exhibits sequence-specific DNA binding and directly interacts with various cellular and viral proteins. p53 is the most commonly mutated gene in human cancer, with the majority of the mutations being amino acid substitutions. The normal function of p53 is to effect cell cycle arrest at the G1 and G2 checkpoints in response to DNA damage. This checkpoint function is executed by accumulation of p53 followed by induction of the GADD45, WAF1 and MDM2 genes. The current model of p53 function postulates that p53 senses DNA damage and arrests the cell cycle in either the G1 or G2 phases to allow DNA repair to take place. If repair is not successful, p53 initiates programmed cell death, thus preventing the propagation of genetic defects to successive generations of cells.
